Dermatome Foot Map – If you’ve ever wondered how the human dermatome chart appears, then you’re at the right spot. Before we get to the map, let’s look at what is a dermatome. What are the different kinds? And most importantly, why is it important to know about dermatomes in order to better understand how the body works. Read on to find out more. You might be surprised! Here are some examples of dermatomes.

What is a Dermatome?

” Dermatomes” refers to the spinal cord “dermatome” refers to a tissue that covers the spine. Dermatomes are important in allowing doctors to construct maps of the spinal cord that can be useful in diagnosing. Two major maps are regarded as valid by medical professionals. They are the Keegan and Garret map and the Foerster map. These maps were made in the 1930s, and are frequently utilized. The trigeminal nerve , as well as the maxillary nerve are among the most extensive dermatomes.

Dermatomes are areas of skin that are attached to a particular nerve. In the case of spinal cord injuries, pain may be experienced in a dermatome that is controlled by the nerve. Similarly, the pain caused by shingles outbreaks can be felt in specific spinal nerves. If you feel neurologic condition or pain that involves the dermatome region, you need to consult a physician.

What are Some Examples of Dermatomes?

Dermatomes are the segments of skin that is provided by one spinal nerve. These nerves provide sensory, motor and autonomic information. They form an element of the peripheral nerve system, that connects the brain to the all the body. A dermatome may get affected because of a spinal cord lesion. When one of these dermatomes gets injured, it is able to be easily treated with a local anesthetic.

Dermatomes in the thoracic region are labeled with letters-numbers that illustrate how the region is connected as well as the nerve that supplies that region. For example the C1 spinal nerve doesn’t have a dermatome. However, others spinal nerves have been labeled as C1-C8 and T9 is a reference to belly button. Dermatomes are layered horizontally on the trunk, however, dermatomes that are located on the extremities are generally linear.

Dermatome Map

The dermatome map is one of the common features of textbooks teaching anatomy. However, the dermatome maps is not consistent both within and inter-textbook. Its name isn’t consistent as are some textbooks that have various maps on different pages. This is particularly problematic in the event that the authors of various chapters are not unified in their choice of dermatome map. Many textbooks use the maps of Foerster, Keegan, and Garrett however they don’t provide adequate references. Moreover, four textbooks use maps with no citations. This includes one that refers to only secondary sources.

Dermatomes are the parts of skin that receives sensory stimulation from the dorsal root of a spinal nerve. Dermatomes aren’t evenly found, but they tend to be more inferior than horizontally. This is an inherent variation and some tissues are covered by more than one dermatome. Additionally, dorsal spinal rootlets may be anastomosed with intrathecal intersegmental sensory neurons in those limbs that are dorsal.
